ABSTRACT: Kinome-wide shRNA screen to identify kinases differentially required for survival of cells disomic and trisomic for chromosome 21 Cells were transduced in triplicate and propagated for 14 days to allow for enrichement or depletion of shRNAs from the population

Although it is clear that trisomy 21 causes Down syndrome, the molecular events acting downstream of the trisomy remain ill defined. Using complementary genomics analyses, we identified the interferon pathway as the major signaling cascade consistently activated by trisomy 21 in human cells. Transcriptome analysis revealed that trisomy 21 activates the interferon transcriptional response in fibroblast and lymphoblastoid cell lines, as well as circulating monocytes and T cells. Trisomy 21 cells s ...[more]

Project description:Trisomy of chromosome 21, the genetic cause of Down syndrome, has the potential to alter expression of genes on chromosome 21, as well as other locations throughout the genome. These transcriptome changes are likely to underlie the Down syndrome clinical phenotypes. We have employed RNA-seq to undertake an in-depth analysis of transcriptome changes resulting from trisomy of chromosome 21, using induced pluripotent stem cells (iPSCs) derived from a single individual with Down syndrome. These cells were originally derived by Li et al, who genetically targeted chromosome 21 in trisomic iPSCs, allowing selection of disomic sibling iPSC clones. Analyses were conducted on trisomic/disomic cell pairs maintained as iPSCs or differentiated into cortical neuronal cultures. Overall design: 12 total polyA selected samples. 6 IPSC samples with 3 biological repeats for trisomic samples and 3 biological repeats for disomic samples. 6 IPSC derived neuronal samples with 3 biological repeats for trisomic samples and 3 biological repeats for disomic samples.

Project description:The effect of CD151 expression onto the kinome of Jurkat T cells was assessed using kinome analysis. CD151 was expressed in Jurkat T cells by retroviral transduction based on a pMSCV vector. Entrez Gene: 977 UniProtKB: P48509 Jurkat T cells were transduced with the MSCV-CD151 vector and successfully transduced cells were selected using puromycin. For the kinome array experiments 3 independent samples of Jurkat cells and three independent samples of J-CD151 cells were collected. To minimize unspecific background signals, lysates from Jurkat and J-CD151 T cells harvested at different growth stages, which were then pooled to provide one sample prior to loading on the Kinexus antibody microarrays.

Project description:Primary human T cells from healthy donors were sorted using a FACSAria II to obtain CD3+CD4+CD151+ and CD3+CD4+CD151- populations. To perform kinome analysis using Kinex™ microarrays, 50 µg of lysate protein from each sample were labeled with a proprietary fluorescent dye according to the manufacturers instructions (Kinexus, Canada). The utilized KAM-850 chips were spotted in duplicates with over 850 antibodies: 510 pan-specific antibodies used in the chip allows for the detection of 189 protein kinases, 31 protein phosphatases and 142 regulatory subunits of these enzymes and other cell signaling proteins. 340 phospho-specific antibodies tracked the unique phosphorylation of 128 sites in protein kinases, 4 sites in protein phosphatases and 155 sites in other cell signaling proteins. The background-corrected raw intensity data were logarithmically transformed with base 2. Z scores were calculated by subtracting the overall average intensity of all spots within a sample from the raw intensity for each spot, and Z score ratios were calculated by dividing Z scores by the standard deviations (SD) of all of the measured intensities within each sample. To minimize unspecific background signals, lysates from cells from 5 different donors were sorted and the corresponding populations were pooled to provide one sample prior to loading on the Kinexus antibody microarrays. 16JN20-KAM880 Kit-K012003211-19123.txt contains the original data for the CD4+CD151- T cell population at baseline. 16JN20-KAM880 Kit-K012003211-19124.txt contains the original data for the CD4+CD151- T cell population following stimulation with 30 U/ml IL-2 for 24 hours. 16JN21-KAM880 Kit-K012003229-19125.txt contains the original data for the CD4+CD151+ T cell population at baseline. 16JN21-KAM880 Kit-K012003229-19126.txt ontains the original data for the CD4+CD151+ T cell population following stimulation with 30 U/ml IL-2 for 24 hours.

Project description:Individuals with Trisomy 21 (T21) exhibit numerous hematological abnormalities, including reductions in numbers of circulating B and T lymphocytes. To elucidate molecular mechanisms underlying these phenotypes, we differentiated human isogenic disomic and trisomic pluripotent cells, and observed that trisomic cells showed defects in B cell, but not T, cell differentiation. Global gene expression of differentiated, trisomic B cells revealed reduced expression of genes encoding endothelin signaling components, namely the Endothelin Receptor B (Ednrb), and its ligand Endothelin1 (Edn1).. Depletion of Ednrb mRNA in cord blood CD34+ cells led to defective B cell differentiation, supporting an hypothesis that low expression of Ednrb in T21 contributes to intrinsic lymphoid defects. Further evidence for the role of the Ednrb pathway in B cell differentiation was obtained through CRISPR/Cas9 gene targeting in disomic and trisomic iPS cells. Knockout of Ednrb in both cell backgrounds reduced the capacity for B cell differentiation. Collectively, this work identifies downregulation of Ednrb as a causative factor for impaired B lymphocyte generation in trisomic cells, which may contribute to defects in immune function associated with T21. Furthermore, a novel role for endothelin signaling in regulation of B cell development has been identified. Overall design: Disomic and trisomic isogenic iPS cells were differentiated in parallel, and after co-culture with MS5 cells, CD45+ CD34- CD19+ cells were isolated by FACS. RNA was extracted using Trizol. Global gene expression analysis by microarray was performed on the Human HG U133 Plus 2.0 platform. Each group contains three biological replicates.

We profiled gene and miRNA expression as well as genome-wide and promoter specific DNA methylation and hydroxymethylation patterns in trisomic and disomic fibroblasts, using microarrays and methylated DNA immunoprecipitation. Overall design: comparison of trisomy 8 cells with disomic as well as reference fibroblasts

Project description:These experiments were done to compare the transcriptional response to high temperature of disomic yeast to that of WT yeast. Total RNA from strains and timepoints specified was labeled by Cy3- this was compared to WT total RNA in all cases.

Project description:Background. Most methods for constructing aneuploid yeast strains that have gained a specific chromosome rely on spontaneous failures of cell division fidelity. In Saccharomyces cerevisiae, extra chromosomes can be obtained when errors in meiosis or mitosis lead to nondisjunction, or when nuclear breakdown occurs in heterokaryons. We describe a strategy for constructing N+1 disomes that does not require such spontaneous failures. The method combines two well-characterized genetic tools: a conditional centromere that transiently blocks disjunction of one specific chromosome, and a duplication marker assay that identifies disomes among daughter cells. To test the strategy, we targeted chromosomes III, IV, and VI for duplication. Results. The centromere of each target chromosome was replaced by a conditional centromere that can be blocked by growth in galactose, and ura3::HIS3, a duplication marker. Transient exposure to galactose induced the appearance of colonies carrying duplicated markers for chromosomes III or IV, but not VI. Microarray-based comparative genomic hybridization (CGH) confirmed that disomic strains carrying extra chromosome III or IV were generated. Chromosome VI contains several genes known to be deleterious when overexpressed, including the beta-tubulin gene TUB2. To test whether a tubulin stoichiometry imbalance prevents viability in cells carrying an extra chromosome VI, we supplied the parent strain with extra copies of the alpha-tubulin gene TUB1, then induced nondisjunction. Galactose-dependent chromosome VI disomes were produced, as revealed by CGH. Some chromosome VI disomes also carried extra, unselected copies of additional chromosomes. Conclusions. This method causes efficient nondisjunction of a targeted chromosome and allows resulting disomic cells to be identified and maintained. We used the method to test the role of tubulin imbalance in the apparent lethality of disomic chromosome VI. Our results indicate that a tubulin imbalance is necessary for disomic VI lethality, but it may not be the only dosage-dependent effect. Keywords: comparative genomic hybridization, CGH Overall design: Candidate disomes (Ura+His+) were compared to their euploid parents by CGH. 27 candidate strains were examined with 27 arrays. 4 candidates targeted chromosome III (3 induced, 1 spontaneous), 14 candidates targeted chromosome IV (8 induced, 6 spontaneous), and 9 candidates targeted chromosome VI (all induced).

Project description:Identifying dynamic protein phosphorylation events is critical for understanding kinase/phosphatase regulated signaling pathways. To date, protein phosphorylation and kinase expression have been examined independently in photosynthetic organisms. Presented here is a method to study the global kinome and phosphoproteome in tandem for the first time in a photosynthetic organism, the model alga Chlamydomonas reinhardtii (Chlamydomonas), using mass spectrometry-based label-free proteomics. A dual enrichment strategy first targets intact protein kinases via capture on immobilized multiplexed inhibitor beads (MIBs) with subsequent proteolytic digestion of unbound proteins and peptide-based phosphorylation enrichment. To increase depth of coverage, both data-dependent and data-independent (via SWATH) mass spectrometric acquisitions were performed to obtain a >50% increase in coverage of the enriched Chlamydomonas kinome over coverage found with no enrichment. The quantitative phosphoproteomic dataset yielded 2,304 phosphopeptides and 1,765 localized phosphosites with excellent reproducibility across biological replicates (90% of quantified sites with coefficient of variation below 11%). This approach enables simultaneous investigation of kinases and phosphorylation events at the global level to facilitate understanding of kinase networks and their influence in cell signaling events.
